Forgotten Words: Benchmarking NeoBERT for Dementia Detection in Low-Resource Conversational Filipino and English Speech

This paper presents the first NLP-based dementia detection study for Filipino speech, constructing a parallel bilingual dataset of 4,000 DementiaBank-derived transcripts with manual Filipino translations. Five model families are evaluated across monolingual, zero-shot cross-lingual, and bilingual fine-tuning settings. English-trained BERT degrades sharply on Filipino (Macro-F1 = 0.455), but bilingual fine-tuning recovers performance to Macro-F1 = 0.969–0.973 across all transformer models. The key finding is that multilingual clinical NLP performance is driven by linguistic coverage during training rather than model scale or architecture.

FilBench: Benchmarking LLM Capabilities in Filipino Language

FilBench is a new benchmark introduced to evaluate large language models on their ability to understand and generate Filipino. The benchmark targets a historically underrepresented language in NLP evaluation suites, assessing both comprehension and generation tasks. This work addresses gaps in multilingual LLM evaluation coverage, particularly for Southeast Asian languages.

Speech-based dementia screening using Whisper embeddings to compensate for nonverbal subtest omissions

Researchers present a speech-based evaluation system for the German Syndrom-Kurz-Test dementia screening battery, combining transcript-derived scores with Whisper embeddings to reduce transcription scoring errors. The system also approximates expert overall ratings even when motor (nonverbal) subtests are omitted, addressing a key accessibility limitation of speech-only assessment. Models show strong correlation with expert ratings and effective discrimination between cognitive status groups.

LLMs predict dementia and depression severity from clinical interview transcripts in zero-shot and feature-extraction settings

Researchers evaluate three open-weights LLMs (Mistral 3.1, DeepHermes, Qwen3) for predicting dementia and depression severity from speech transcripts of 154 German-speaking patients in standardized clinical interviews. The study introduces a new observer-based Global Depression Scale (GDS-D) and tests both zero-shot prediction and LLM-based feature extraction for Support Vector Regression. Zero-shot performs well for depression (MAE 0.60), while structured feature extraction reduces dementia assessment error by up to 35%; pause-enriched automatic transcripts match human transcription quality, suggesting viable fully-automated screening pipelines.

Sentence-Level Clinical Provenance Categorization for Multidisciplinary Hospital Summarization Using Fine-Tuned Llama-3

This pilot study presents a pipeline for categorizing sentence-level clinical provenance across multi-source hospital notes, targeting structured summarization in high-complexity settings like the NICU. The authors fine-tune Llama-3 8B and 70B models on MedSecId (MIMIC-III annotations), achieving Macro F1 above 92% in-domain. Cross-domain evaluation reveals a scale-dependent transfer effect: SFT substantially improves the 70B model (+7% Macro F1) but yields only marginal gains for the 8B model. A quantized fine-tuned 70B model outperforms its full-precision baseline while reducing compute, suggesting quantized adaptation is viable for structured clinical NLP tasks.

IndicBERT-HPA: Reliability-Oriented Multilingual Orthopedic Decision Support with Selective Verification Deferral

This paper presents a framework for classifying free-text orthopedic clinical notes in English, Hindi, and Punjabi, introducing IndicBERT-HPA, a domain-adaptive encoder augmented with language-aware orthopedic adapter heads. The system is evaluated against multilingual transformers, a DistilBERT baseline, and zero-shot LLMs, with zero-shot LLMs found substantially less effective than task-adapted encoders for closed-set clinical classification. IndicBERT-HPA achieves Macro-F1 of 0.8792 and AUPRC of 0.902 under natural clinical prevalence. A deterministic selective-verification layer combining confidence gating, evidence-consistency checking, and language-risk screening improves accuracy from 71.5% to 84.4% at 72.3% coverage on a 5,000-record held-out set.

Automated ICD Classification of Psychiatric Diagnoses Using NLP and LLMs

This study evaluates NLP and ML approaches for automating the mapping of free-text psychiatric descriptions to ICD diagnostic codes, using a dataset of 145,513 Spanish clinical records. Methods range from classical BoW/TF-IDF representations to transformer-based embeddings including e5_large, BioLORD, and Llama-3-8B. Fine-tuned e5_large achieved the best performance with a micro-F1 of 0.866, outperforming classical methods by capturing semantic nuance and medical terminology. The work highlights challenges of long-tail label distributions and ambiguity specific to psychiatric clinical language.

ENPMR-Bench: Benchmarking Proactive Memory Retrieval for Emotional Support Agents

This paper introduces ENPMR-Bench, a benchmark for evaluating Emotional Need-aware Proactive Memory Retrieval in memory-augmented language agents deployed for emotional support applications. The benchmark includes over 1,800 memory-augmented dialogues grounded in Maslow's hierarchy of needs, with structured mappings between emotional needs and supportive memory types. Experiments show that both embedding-based and LLM-driven retrieval paradigms fall significantly short of golden memory conditions on empathy scores, and while chain-of-thought prompting helps, a substantial performance gap remains. The work highlights a systematic gap in current agent memory systems when applied to affective rather than purely factual retrieval tasks.

BayLing-Duplex: Native full-duplex speech dialogue using a single autoregressive LLM

Researchers introduce BayLing-Duplex, a speech language model that achieves native full-duplex interaction — simultaneous listening and speaking — using a single autoregressive LLM with no auxiliary VAD or turn-taking module. Built by fine-tuning GLM-4-Voice on 400K samples plus a lightweight DPO stage, it reaches 92% turn-taking success and 100% interruption success on InstructS2S-Eval, and improves speech-response quality substantially over Moshi. The approach adds only special tokens to the standard vocabulary, making it portable across LLM architectures without architectural changes.
